Description

When compiling Arrow with the following parameter:

-DARROW_BUILD_BENCHMARKS_REFERENCE="ON"

I get this error and other similar ones:

cpp/src/arrow/io/memory_benchmark.cc:244:26: error: use of undeclared identifier 'Read'; did you mean 'read'?
using ApplyFn = decltype(Read);

 

The reason is that `memory_benchmark.cc` does not define the Read function, and others, if the SIMD level is NEON (`ARROW_HAVE_NEON` is true).
